CORNER PLATE, STRIP, OR BEAD AND CLIP THEREFQR.

SPECIFICATION forming part of Letters Patent No. 682,489, datedSeptember 10, 1901. Application filed December 11, 1900. Serial No.39,581. (No model.)

T0 on whom it may concern:

Be it known that I, WILLIAM F. PARKER, a citizen of the United States,residing at New York city, in the county and State of New York, haveinvented new and useful Improvements in Corner Plates, Strips, or Beadsand Clips Therefor, of which the following is a specification.

My present invention relates to certain new and useful improvements incorner plates, strips, or beads for protecting the angles of plasteredwalls, and in an improved form of clip for attaching the corner plate,strip, or bead to the angle of a wall, whereby the same will besupported in a firm and rigid manner.

It is one purpose of the invention to provide a corner strip, plate, orhead of T shape in cross-section formed from a thin strip of sheet metalbent and folded upon itself to provide a narrow longitudinal plasteredge or bead at the front thereof and laterally-ex tending plasterinterlocking and clip-engaging flanges at the rear of the plate, strip,or head which extend at right angles to the web or body thereof, saidweb or body being preferably provided with plaster-receiving openings,whereby the plaster will be firmly held to the plate, strip, or bead.

It is a further purpose of the invention to provide a novel form of clipformed from a single blank of sheet metal and having lips or tonguesstamped therefrom and arranged to embrace the flanges of the plate,strip, or bead and support the same in a firm and rigid manner.

It is another purpose of the invention to provide a corner strip orplate with a longitudinal plaster-bead along one edge and longitudinalflanges along the opposite edge which extend at rightangles to the Webor body of the plate or strip in such manner as to provide a dovetailedspace for the looking or keying of the plaster between said plasterbeadand flanges upon opposite sides of the plate or strip.

It is still another purpose of the invention to provide a strip, plate,or head with a broad face or wall along its inner or rear longitudinaledge to constitute a flat surface cooperating with a flat surface on theclip, whereby a firm and secure corner is provided.

To these ends the invention comprises the novel features of constructionand arrange ment of parts hereinafter described in detail and then moredefinitely pointed out in the claims.

In the annexed drawings, illustrating the invention, Figure 1 is aperspective View of my improved strip, plate, or head having a clipattached thereto. Fig. 2 is a sectional view of the plate or head andclip attached to the angles of a wall. Fig. 3 is a plan. view of theblank from which the clip is made. Fig. 4 is a sectional View of aplastered corner, showing theplate, strip, or bead in position and themanner in which the plaster interlooks or keys therewith between thelongitudinal bead and flanges or angular extensions.

Figs. 5 and 6 are views illustrating slightlymodified forms of myinvention.

My improved corner plate, strip, or head, which is of T shape incross-section, is formed from a single strip of sheet metalbentintermediate its ends along a central line, and at the point ofbending the metal is flattened and shaped to form a bead 1, that extendslongitudinally throughout the entire length of the strip at the frontthereof. The two thicknesses of metal are then brought together toprovide a web or body 2, which is preferably provided with plasteropenings or slots 3, although these may be omitted, if desired. The freeends 4 of the metal strip are then bent outwardly at right angles to theweb or body 2, so as to provide a substantially dovetailed plasterkeying or looking space on each side of the plate between saidright-angled extensions or flanges 4 and head 1, as clearly illustratedin Fig. 4. As shown in the drawings, the bead 1 projects laterally oneach side of the web or body 2 and provides a straight edge,constituting the angle or cornerproper of the wall. The two rightangledextensions or flanges 4 are bent in opposite directions and lie in thesame plane, so as to provide a broad longitudinal supporting-face tocodperate with the fiat face of a clip now to be described.

My improved clip is formed from a single blank 5, (shown in Fig. 3,) andis provided upon opposite sides of a central line, taken transverselytherethrough, with s ubstan tially U -shaped slits or cuts 6. The metalbetween said slits or cuts is bent upward and toward each other toprovide lips or tongues 7, that are arranged to engage or embrace theflanges 4 of the strip or plate and support the latter in use. Whenshaped to operative form, the clip comprises two members 8, arranged atright angles to each other, and each member is provided with a pluralityof nail or tack openings 9. Near its center the blank 5, forming theclip, is bent transversely on two lines, as at 10 10, each bent portionextending outwardly at an obtuse angle to one of the members 8 toconstitute an extension 12, having a flat supporting face or wall 13,against which rests the flat face formed by the flanges 4 of the cornerstrip or plate, whereby a firm and rigid structure is provided. As shownin Figs. 1 and 2, the lips or tongues 7 of the clip are caused toembrace the flanges 4 of the plate or strip and engage the web or body 2thereof, and thus hold and support the same against lateral movement.

I regard the particularcross-sect ional sh ape of the strip or plate asbeing of considerable importance, since it provides a rigid structu reand maintains a perfectly straight plaster edge throughout. It providesan efficient lock or key for the plaster and affords a broad supportingface or wall for the clip. As shown in Fig. 4, when the angle of thewall is plastered or finished the lateral flanges or extensions of thestrip or plate will be firmly embedded in the mortar or plaster, and aperfect union of the whole structure is thereby secured.

In Figs. 1 and 2 of the drawings I have shown my improved corner plateor strip and bead as supported or held to the angle of a wall by meansof a novel form of clip; but I do not wish to be understood aslimiting'rnyself to this specific manner of attaching or supporting theplate or strip, for it will be obvious that the same may be employed inconnection with other forms of supporting means, such as a reticulatedstrip, as shown in Fig. 5. In this embodiment of the inven tion thenumeral 14 designates the bead-piece, and 15 the web or body portion ofthe strip or plate, the two folds or walls of which are slightlyseparated to receive the doubled portion 16 of a bent strip ofwire-netting, the two wings 17 of which are shaped to straddle the angleor corner of the wall. The plate or strip is preferably provided withplasteropenings 18 to admit the plaster, whereby the latter is firmlybound to the plate or strip and wire-netting and whereby these parts aremore securely locked together.. The headpiece 14 may also, if desired,be provided on opposite sides with sharp edge projections 19,substantially as shownin my Patent No. 640,410, and is likewise formedwith outturned flanges 20, according to the present invention.

In Fig. 6 I have shown a slightly-modified form of plate or strip andbead, the object being to add greater strength and rigidity thereto. Inthis figure the numeral 21 designates the bead, 22 the web or bodyportion, and 23 the outturned or lateral flanges, which latter are bentor folded back, as at 24, to give a double thickness of metal at thesepoints, which adds materially to the strength and rigidity of the plateor strip.

What I claim as new is 1. A corner plate or strip comprising a web orbody portion having flanges extending outwardly from the inner edgethereof at right angles to said web or body portion.

2. A corner plate or strip comprising a web or body portion having alongitudinal bead along one edge and lateral flanges along its oppositeedge, said flanges extending outward from opposite sides of the plate orstrip and arranged at right angles to the web or body portion.

3. A corner plate or strip formed from a sheet-metal strip bent andfolded upon itself to provide a web or body portion having a bead alongits front edge, the free longitudinal edges of said strip being bentoutward at a right angle to said web or body portion and projecting fromopposite sides thereof.

at. A corner plate or strip formed from a single sheet of metal bent andfolded upon itself to provide a web or body portion having a bead alongits front edge and rightangled extensions at its rear edge projectingfrom opposite sides of the plate or strip, said web or body portionbeing provided with plaster-openings.

5. A corner plate, strip or head having a T shape in cross-section, andmeans for supporting the same removed from the angle of a wall.

6. A corner plat-e, strip or bead having a T shape in cross-section,combined with a clip having ears or lips embracing the opposite sides ofsaid plate along the inner longitudinal edges thereof.

7. The combination with a corner-strip comprising a web or body portionhaving flanges extending outward from opposite sides thereof, of a cliphaving a flat face to receive and support said flanges, and means forlocking the strip and clip together.

8. The combination with a corner-strip comprising a web or body portionhaving flanges extending outward from the inner edge thereof uponopposite sides, of a clip having a flat face to receive and support saidflanged portion of the strip, and lips or tongues formed integral withthe clip and embracing said flanges upon opposite sides to lock theparts together.

9. A corner plate or strip comprising a web or body portion havinglateral flanges extending outward from the base thereof, said flangesbeing folded back upon themselves to provide double thicknesses of metalat these points.

10. A clip comprising two members arranged at an angle to each other andhaving an intermediate extension provided with a flat face or Wall, andlips or tongues formed eeaese IO and lips or tongues stamped from saidstrip I upon opposite sides of the extension and overhanging the saidface or Wall.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
